Résumé :

Photovoltaic greenhouses became popular in many countries for growing crops and, at the same time, generating electricity mainly for own usage to control the air temperature inside the greenhouse. Solar radiation is essential for their photosynthesis process for crop growing, however, high levels of solar radiation may adversely affect the crop quality. Therefore, a balance between the need for sufficient solar radiation for plant grows and the need for electricity is important to maintain. Many greenhouses are built with curved rooftops of convex shapes and flat-plate photovoltaic (PV) module

Résumé :

This paper aimed to investigate the temperature effect on photovoltaic (PV) cell parameters. The PV cell parameters such as series and parallel resistances, diode ideality factor, and diode saturation current, are not considered in the reported stepwise modeling. The present work aims to improve available models used in the modeling and simulation of PV modules to support the researcher and power project developer. All the required temperature-dependent parameters are determined to model the simulated PV module with high accuracy using Simulink/MATLAB software. To validate the method, a 36-cel

Résumé :

This paper studies the power generation performance of flexible solar panels at different radii of curvature for both concave and convex configurations. Its performance is evaluated horizontally and vertically to provide architects and designers with a reference of how power generation is impacted depending on the geometries selected for the design of facades or roofs. The study consisted of two phases, the first comprised a simulation to estimate the amount of energy a surface receives according to its geometry, orientation, location, and simulated period. The second phase corresponds to an e

Résumé :

In the developing landscape of photovoltaic (PV) technology, accuracy in simulating PV cell behaviour is dominant for enhancing energy conversion efficiency. This study introduces a new approach for parameter estimation in the three-diode PV model, a basis in the representation of PV cell characteristics. The methodology combines a reinforced learning-based parrot optimizer (RLPO) with an adaptive secant method (ASM) to fine-tune the parameters governing the PV model. The RLPO algorithm is inspired by the mimetic ability of parrots, i.e., foraging, staying, communicating, and fear noticed in t

Texte intégral

Résumé :

To improve the surface morphology quality of ultra-precision optical components, particularly in the suppression of mid-spatial frequency (MSF) errors, this paper proposes a morphology gradient-aware spatiotemporal coupled smoothing model based on convolutional material removal. By introducing the Laplacian curvature into the surface evolution framework, a curvature-sensitive “peak-priority” mechanism is established to dynamically guide the local dwell time. A nonlinear spatiotemporal coupling equation is constructed, in which the dwell time is adaptively modulated by surface gradient magnitud

Résumé :

The hydraulic system drives the cutter head mechanism to realize the excavation of large tunnel boring equipment, which puts forward the technical requirements of high pressure and large flow to the pump source. The traditional small displacement axial piston pump uses a planar valve plate. However, under high flow and heavy load conditions, the planar valve plate configuration is prone to uneven wear due to the high-pressure and -velocity (PV) value and pressure shock, which ultimately affects the reliability of the system.

Résumé :

Photovoltaic (PV) wall panels are an integral part of Building-Integrated Photovoltaics (BIPV) and have great potential for development. However, inadequate heat dissipation can reduce power generation efficiency. To reduce the temperature of photovoltaic wall panels and improve the photovoltaic conversion efficiency, this paper constructs a computational fluid dynamics (CFD) numerical model of ventilated photovoltaic wall panels and verifies it, then simulates and analyzes the effects of three cavity structure forms on the thermal performance of photovoltaic wall panels and optimizes the dime

Résumé :

The integration of photovoltaic (PV) systems into tensioned membrane structures presents a significant advancement for sustainable applications in the built environment. However, a critical technical challenge remains in the substantial strains induced by external loads, which can compromise both PV efficiency and the structural integrity of the membrane. Current design methodologies prioritize stress, deflection, and ponding analysis of tensioned membranes. Strain behavior of whole structures, a key factor for ensuring long-term performance and compatibility of PV-integrated membranes, has be

Résumé :

Conventional life theory defines the rolling contact fatigue (RCF) life as being determined by the maximum contact pressure (P) and the total number of stress cycles (N). However, when the life test results of bearings were analyzed, it was found that there were cases where there was little correlation between the RCF life, maximum contact pressure and the number of stress cycles. An extensive investigation has revealed that the slip velocity is an additional factor that influences the RCF life of bearings. Under special test conditions it was discovered that when the PV value, which is a prod

Résumé :

A new type of Twymann-Green interferometer developed here mainly consists of a collimated He-Ne laser beam, a holographic optical element (HOE), a reference flat mirror, an imaging lens, and a screen. The HOE is made using a collimated reference beam and a diverging spherical object beam. In the interferometer the HOE, illuminated from its back by a collimated beam, diffracts a spherical wavefront and transmits the collimated beam. The former beam is reflected by a spherical mirror under test, passes through the HOE, and reaches to a screen. The latter beam is reflected by a flat reference mir
